Abstract Details


To compare choroidal thickness and ocular pulse amplitude between patients with essential thrombocythemia and healthy adults.


Pamukkale University Ophthalmology Department, Denizli, Turkey


A total of 74 participants (37 eyes of 37 patients in essential thrombocythemia group, and 37 eyes of 37 age-sex-matched healthy adults in control group) were recruited in this prospective, cross-sectional, and comparative study. The OCT measurements were done with spectral-domain OCT (Spectralis, Heidelberg, Germany) for subfoveal choroidal thickness. The Pascal dynamic contour tonometer (Swiss Microtechnology AG, Port, Switzerland) was used for OPA and IOP measurements.


The mean age of the study group was 57.4 ± 16.9 years and the mean age of the control group was 56.5 ± 10.0 years (p=0.77). There were no statistically significant differences between the study group and the control group in the aspect of subfoveal choroidal thickness, ocular pulse amplitude, and intraocular pressure measurements (p>0.05).


Both anatomical (subfoveal choroidal thickness) and physiological (ocular pulse amplitude) choroidal parameters were similar between patients with essential thrombocythemia and controls, indicating that choroid is protected from systemic hematological threats to some extent.
